P1762 INFINITI, NISSAN: DIRECT CLUTCH SOLENOID VALVE
Description of DTC code P1762
In order to determine the most appropriate gear to use depending on driving conditions, the TCM (Transmission Control Module) relies on various information provided by sensors and switches, including the Neutral Park Position Switch, Throttle Position Sensor, and Vehicle Speed Sensors. Although these operating parameters directly affect the performance of the direct clutch solenoid valve, the function of the ATF 5 pressure switch is also affected.
The P1762 OBDII diagnostic code is a code that, in the case of Infiniti and Nissan vehicles, relates to a malfunction of the Direct Clutch Solenoid Valve.
To troubleshoot the DTC P1762 OBDII code consider the following:
Consult as a first step the Technical Service Bulletins (TSB).
Inspect all the wiring of the Direct Clutch Solenoid Valve for common damage caused by burns or corrosion. If such conditions are found, correct them as applicable.
Perform voltage tests on the Direct Clutch Solenoid Valve circuit and verify that the Direct Clutch Solenoid Valve circuit is not open. If deficient voltages are detected, proceed with appropriate corrections.
Measure the resistance of the Direct Clutch Solenoid Valve and compare it to the manufacturer's specifications. If you detect an out-of-range resistance, it is indicative of damage to the solenoid requiring replacement.
